Повний текст джерелаG15 is a heterotrimeric G protein of the Gq/11 family. In this study, we describe its exceptional poor sensitivity to the general regulatory mechanism of G protein-coupled receptor (GPCR) desensitization. Enhancing β2 adrenergic receptor desensitization by arrestin overexpression, did not affect signalling to G15. Similarly, increased levels of arrestin did not affect G15 signalling triggered by the activation of V2 vasopressin and δ opioid receptors. Furthermore, co-immunoprecipitation experiments showed that G15 α subunit (as opposed to Gαq and Gαs) is recruited to a V2 vasopressin receptor mutant that is constitutively desensitized by β-arrestin. Interestingly, co-expression of G15 partially rescued cell surface localization and signalling capabilities of the same mutant and supported its sustained activity on downstream effectors including PKD1. However, differential modulation by the agonist was observed while comparing effectors activity to receptor internalization. Taken together, these findings provide evidence for a novel mechanism whereby GPCR desensitization can be bypassed and G15 can support sustained signalling in cells chronically exposed to hormones or neurotransmitters. This aspect led us to hypothesize that G15 presence could be associated to poorly regulated physiological states, and in particular with tumor formation. A screening demonstrated Gα15 presence in 10 out of 40 human cancer cell lines analyzed, all derived from a variety of tissues reported as negative. Gα15 mRNA and protein were also found in pancreatic and prostate tumor biopsies. Notably, Gα15 was present in the proliferating fraction of the tumor as demonstrated by xenotransplantation of the tumors in nude mice.
FOCACCETTI, CHIARA. "Inibizione immunologica del processo di cancerogenesi nei tumori della mammella insorti in topi BALB/c transgenici per il prodotto dell'oncogene ErbB2/neu mediante immunoterapia attiva."

Повний текст джерелаEmploying the transgenic animal model BALB-NeuT, the outcome of neu-mediated tumorigenesis was compared following vaccination with isogenic normal rat ErbB2/Neu (LTR-Neu) or xenogeneic human ErbB receptors (LTR-EGFR, LTR-ErbB2, LTR-ErbB3 and LTR-ErbB4), both recombinantly expressed in an NIH3T3 murine cell background, or following vaccination with neu-recombinant Vaccinia virus (rV-neu). Vaccination using rat LTR-Neu at the stage of atypical hyperplasia potently inhibited neu-mediated mammary tumorigenesis. Moreover, all human ErbB receptors specifically interfered with tumor development in BALB-NeuT mice. Relative increase in tumor-free survival and reduction in tumor incidence corresponded to structural similarity shared with the etiologic neu oncogene. The rat orthologue LTR-Neu proved most effective followed by the human homologue LTR-ErbB2 and then the other three human ErbB receptors. Vaccination resulted in high titer of specific serum antibodies whose tumor-inhibitory effects correlated with cross-reactivity to purified rat Neu extracellular domain in vitro. Furthermore, a T cell response specific for peptide epitopes of rat Neu was elicited in spleen cells of mice immunized with LTR-Neu and was remotely detectable for discrete peptides upon vaccination with LTR-ErbB2 and LTR-EGFR. The most pronounced tumor inhibition by LTR-Neu vaccination was associated with leukocyte infiltrate and tumor necrosis in vivo, while immune sera specifically induced cytotoxicity and apoptosis of BALB-NeuT tumor cells in vitro. Moreover, the multiple vaccination employing the neu-recombinant virus also resulted in a specific inhibition of neu-mediated tumorigenesis. The resulting inhibition was comparable with the allogeneic immunization schedule when started early in tumor development but gave higher protection when the vaccination was started later in tumor onset.

Повний текст джерелаHepatocellular carcinoma (HCC) represents the sixth most common cancer in the world, and the third most frequent oncological cause of death. Over 80% of HCC develop from cirrhosis, mainly related to viral etiology. The prognosis of HCC is mostly poor, because of its late detection at an advanced stage. Thus, new effective biomarkers are needed. MALDI imaging mass spectrometry (MALDI IMS) allows differential distribution visualization of potential markers within tissue. The aim of the present project was to investigate, using MALDI IMS, the proteome of HCC and to compare it with peritumoral cirrhosis so as to characterize new biomarkers of HCC. We found a set of proteins/peptides with a differential intensity level that most accurately delineated cancer from adjacent cirrhotic tissue. We generated a classification model enabling correct classification of most spectra present in cirrhosis or tumor areas from the independent validation group. The most discriminating marker (m/z 8,565) increased in HCC was characterized as the monomeric ubiquitin and further validated by immunohistochemistry. Marker m/z 2,753 was a peptidic fragment of albumin and was overexpressed in HCC while m/z 3,195, identified as a fragment of the alpha chain of hemoglobin, was specifically more intense in cirrhosis. This work provides complementary tools that could be useful in the early diagnosis of HCC. Identified biomarkers will gain further insights in the role of proteasome in the liver cancerogenesis. MALDI IMS and identification developed methods will be useful for other projects

Повний текст джерелаRecent studies show that the intracellular calcium homeostasis, as well as expression and the activity of ionic channels play an essential role in the control of cell proliferation as weIl in a physiological context as in certain cancers. However, no approaches offering ionic channels as therapeutic target is nowadays envisaged as part of the treatments of the cancers of the prostate. ln the present work, we showed the expression, functionality and involvement of calcium-activated potassium channels (IKCa1) in the proliferation of the human prostate cancer cells. These studies also showed that the activation of the IKca1 channel favours the calcium entry via a member of the TRP family of calcium channels, TRPV6, in the prostate cancer cells. Besides, by studies of co-immunoprécipitations, we showed that the IKca1 potassium channel and the TRPV6 calcium channel form a functional molecular complex allowing the calcium entry and the proliferation of the prostate cancer cells. Moreover, a down-regulation of the 1Kca1 channel leads to the neuroendocrine differentiation of the human prostate cancer cells. This suggests an essential role played by the 1Kca1 channel to favour growth or lead to cell differentiation. Our immunohistotluorescence studies also showed an overexpression of IKca1 mRNA and protein in human prostate cancer compared to non-tumor tissues. These data would allow to propose these ion channels as markers and/or as potential therapeutic targets in the treatment of the human prostate cancers
